Seven countries signed a treaty binding each of them to perform
specified actons on a ceratin fixed date, with the actions of each
conditional on simultaneous action taken by the other countries. Each
country was also to notify the six other countries when it had
completed its action.The simultaneous -action provision of the treaty leaves open the possibility that

    

 

    

(A)the compliance date was subject to postponement ,according to the terms of the treaty.

    

 

    

(B)one
of the countries might not be required to make any changes or take any
steps in order to comply with the treaty, whereas all the other
countries are so required

    

 

    

(C)each country might have a well-founded excuse,based on the provision, for its own lack of compliance.

    

 

    

(D)the
treaty specified that the signal for one of the countries to initiate
action was notification by the other countries that they had completed
action.

    

 

    

(E)there was ambiguity with respect to the date after which all actionscontemplated in the treaty are to be complete.

逻辑应该是互相等待以致死锁，我选的是D，答案是C。难道是因为D是说明原因而非一中可能性？就错在这里吗？

In several nineteenth-century paintings the marble  buildings of the Acropolis in Athens are portrayed as  
being reddish, but the buildings do not now appear  reddish. The marble’s natural color cannot have changed  
since the nineteenth century, so the paintings must not  be showing the color of the buildings as they actually  appeared.  
　  
Which of the following, if true, most seriously  undermines the argument above?  

A    The Acropolis can be clearly seen from virtually any location within the city of Athens.  
B    Tiny
        plants
        called
        lichens
        living on marble can  cause the marble to appear reddish.  
C    Many nineteenth-century artists strove for true-  to-life accuracy in every detail of their paintings.  
D    Some types of marble are naturally reddish, whereas  other types are greenish or white.  
E   Not all nineteenth-century paintings of the Acropolis show the marble buildings as being reddish.  
答案：(B)那么C呢？？？

omega公司分发400w份产品目录促销，有两版本，1是对产品添加“手工制造”的描述标签2没有这种标签，收到1的消费者购买量是比收到2的多20%，因此这种标签起了作用，驳斥之

答案是A得到1目录的消费者之前邮购过omega产品

另有D不明白，Omega公司寄送的目录中，1类目录是2类目录的三倍？？？为什么不是这个

第一题：

D选项是在重复Each country was also to notify the six other countries when it had completed its action.这种行动，并不能作为其他国家违背同时行动原则的理由。

第二题：

原文大意：

19世纪的油画将大理石建筑描绘成了淡红色，但实际上现在这些建筑都不是淡红色的，因为大理石不会自己变色。

所以，油画家是错误的。

C选项，说19世纪的油画家精准的描绘了建筑的本色。也就是说，有画家是没错的。这只是在直接反对结论。而没有对结论形成的原因进行反驳。所以错误。

要反对一个结论，最好方法是反对结论借以产生的前提。而不是直接反对结论。

比如，张三说房子是红的，你不能偏说房子是绿的，这不是戗火么？你最好的办法就是让他的前提立不住脚。

再者，C选项说画家没问题，可是没有反驳大理石有问题的前提，那么到底是什么导致了大理石变色呢？还是B选项说的原因。

第三题，

请注意，

原文说的是“购买量大”，不是“收到人数多”。很明显，D选项说的是消费人数上多，这并不能必然导致购买量大。

第三题不就是要驳斥吗？如果证明无效就应该是正确选项了。

A是给出它因的削弱。D无法确定300%的投入与20%的增长是否合理。就无法判断是削弱还是加强。

谢谢sophiaruan的提醒，想着想着就想歪了，差点误导别人。

谢谢啦，不过OMEGA这题还是没怎么明白

D表明了1类目录寄送人群更大，也就削弱了标签导致购买量增加的因果关系，因为宣传面越大，购买越多也是一种逻辑呀

我开始就是这么理解的

mousebrother

谢谢啦
不过虽然D无法确定但也是一定程度上的削弱啊，我认为...A也无法证明从前购买过与这次增加购买量的必然关系啊

mousebrother

或者说以前购买的量也算进去了？收到1类目录的人群的120%包括了之前购买的？
